CABLE-GRIP.

T0 all whom it may concern:

Beit known that I, JOHN S. SPARKS, a citizen of the United States, residing at Bessemer, in the county of Jefferson and State of Alabama,` have invented a new and useful Improvement inCable-Grips, of which the following is a specification.

This invention relates to cable-grips, and more particularly to grips used on miningcars Where cables are used for haulage, the object being to provide an arm with a camshoe adapted to `engage the cable connected to the draw-bar ofthe car.

Another object of my invention is to provide a grip so constructed that it can be readily connected or disconnected from the running cable.

With these objects in view my invention consists, essentially, in the employment of a forked arm provided with a grooved lug which is adapted to fit under the cable, said arm being provided with a cam-shoe having a grooved face, the upper end of said shoe being connected to the draw-bar of the car.

The invention consists also in certain details of construction hereinafter fully de-- scribed, and pointed out in the claims.

In thel drawings forming a part of this speciiication, Figure l is a perspective view of the grip, showing it attached to a cable supported between the track. Fig. 2 is a side view of the grip attached to a cable. Fig. 3 is an end view of the grip. Fig.f4. is a perspective view of the supporting-arm. Fig. 5 is a perspective view of the shoe. Fig. 6 is a perspective view of the draw-bar; and Fig. 7 is a side view of a modification, showing it attached to a cable.

Referring to the drawings, A indicates a railroad track; B, the cable, mounted on supports C, andL D the grips, connected to the cable. l

The grip D consists of a forked arm E, having an enlarged downwardly-extending member F, formed on one of the forked members of the arm, provided with an outwardly-projecting grooved lug F, adapted to fit under the c'able B. A lever G is mounted on a bolt II, secured between the end of the forked member of the arm F, and is provided at its lower end with a cam-shoe I, provided with a grooved face I. The upper end of the lever 1s reduced and apertured and is secured in the bifurcated end J of the draw-bar J by a Specification of Letters Patent.

bolt passing through openings formed in the walls of the bifurcation. The draw-bar J eX- tends through the forks of the cam F between the antifriction-rolls K', mounted on bolts K, and the other end of the bar is forked, having apertures formed in its members, in which a coupling-pin L is adapted to be secured.

In the modification shown in Fig. 7 the grip is especially adapted to be used where the cable passes over the car, the forked arm M being formed with a similar lug M and is provided with an upwardly-projecting member M2, to which the cam-shoe N, carried by the lever N, is pivoted, the lever N being connected to the draw-bar O in a similar manner. A

I-Iaving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the kind described, the combination with a forked arm, of a shoe pivoted to said arm, and a draw-bar passing through said arm connected to said shoe, for the purpose described.

2. In a device of the kind described, the combination with a forked arm having a grooved lug, of a lever pivoted in said arm provided with. a cam-shoe, and a draw-bar passing through said arm connected to said lever, for the purpose described.

3. In a device of the kind described, the combination with a forked arm having an enlarged member, of a grooved lug arranged on said member, a lever pivoted in said arm provided with a cam, having a grooved face, and a draw-bar connected to the upper end of said lever, for the pur ose described.

4. In a device of tlie kind described, the

combination with a forked arm having antl- IOO between said rollers, for the purpose described.
